You guys might have encountered PDF files with password protection sometime or the other.
Its easier to hack those password protected files now with UBuntu.
You wouldnt be needing those KD sucking software anymore.
Go to console/terminal, type the following code.
$ pdftops protected.pdf out.ps
$ pstopdf out.ps out.pdf
Where,
protected.pdf is the protected PDF file
out.ps is an intermediate output of the protected PDF file
out.pdf is the final cracked PDF file
Thats it for the day. More hacks to come.

Soul:
Just for the sake of trying it out, I created a password-protect PDF file (with pdftk), and then tried to convert that file to postscript using pdftops (as you’ve shown). It fails with an “Incorrect password” error.
So, I tried another tool called ‘pdfcrack’ and it actually found what my password is in about 3 minutes (of course, my password is just the word ‘test’ — it probably needs much more time for longer passwords).

This look very interesting to try out.. perhaps when I get to the office tomorrow I’ll give it a try

It works well with me Yousef.
I did it for Acrobat 6.0 pwd protected document.
Let me check into which versions of PDF files are being cracked and related dependencies.
